Rocket Road Trip: Watch a new video series on NASA's human spaceflight program

Way down south in the United States, NASA's human spaceflight centers are in the midst of a once-in-a-generation transformation.

From Florida to Texas, five NASA facilities have designed, built and flown its rockets for more than half a century. After the space shuttles retired in 2011, the agency has been working a new rocket called the Space Launch System, and a crew capsule called Orion. They are part of a plan to send humans beyond low-Earth orbit for the first time since 1972.

To see how these programs are doing, The Planetary Society went on 10-day, 450-mile journey throughout the South. We called it the Rocket Road Trip.

So strap in, fuel up and prepare to launch into this five-part video series featuring a behind-the-scenes look at NASA's deep space human exploration program.
